It costs $288 to sponsor one child for a year through Save the Children.
This means Bill could sponsor 4.16 billion children. Of course, only
about 58.4 million people (adults included) live in all of Ethiopia, and the
world's population is just about 6 billion.

The average per-capita income in New York City is $34,459. Bill could employ
the entire city - men, women, and children - for three years and
four months.

In fiscal 1998, the US Department of Defense's budget totaled $255 billion.
Bill could hire the entire US military establishment for nearly
four years.

As of June 16, 1999, the US population was roughly 273 million.
If we all got together and wanted to make someone besides Bill a billionaire,
it would require a donation of just $3.66 from everyone. On the other
hand, to make someone a trillionaire would require $3,666.35 from
every US citizen.
